Buying Guide
What should you consider when choosing a propeller cover?
- Propeller diameter compatibility: Most covers fit 12″–15″ OD; verify your prop’s outer diameter before buying.
- Material and weather resistance: For outdoor storage and trailer hauling, look for 420D or 600D Oxford fabrics with waterproof coatings and UV resistance.
- Fit and installation: Consider covers with side zippers, buckle straps, or hook-and-loop closures for easy on/off and a snug fit to reduce wind flapping.
- Protection scope: All-round protection against rain, snow, dust, and scratches is ideal for year-round storage; twin-prop covers can be advantageous for boats with dual props.
- Durability vs. weight: Heavier fabrics offer better protection but may be less convenient for quick access; balance handling with expected storage conditions.
